For a total novice (as I am), when read cover to cover without concentrating too much on the exercises or vocab, this book is not bad for an introductory overview of the language. As something to work through though, for me, it dedicates too much time on the connotations of affixes and suffixes. While I can see an analysis of them is necessary to a certain extent, for example in order to be able to isolate a verbal root when conjugating into the passive (don't believe anyone when they tell you Bahasa Indonesia has no conjugations!), there is far too much focus on the changes in meaning caused by the various affixes and suffixes.
The authors write that "the purpose of the discussion is to help identifying the meaning of a given verb and getting an accurate feeling for its place in relation to the other words in a sentence...we are not inviting anybody to make up forms for themselves!" If this is the case, then why not just quickly cover the mechanisms of the aff-/suffixes and their general connotations, and leave the student to appreciate the nitty-gritty of their semantic modification to a more advanced stage? With the space saved, they could have covered much more in terms of sentence construction, grammar, and words more useful to a beginner than learning that -an when suffixed to kudis (scabies) creates kudisan, meaning 'suffering from scabies, mangy'. (!)
While there is a lot to get stuck in to here, I would also say this is not the best book for self-study. A large part of the book is taken up by exercises which have no corresponding answer section. Are they in a teacher's edition?
